2. Manufacture of metallurgical coke
2.1 Overview of conventional coking
With the closure of most of Europe's coal mines, mining coking plants have all but disappeared, replaced by steelmaking coking plants integrated into steelmaking sites, often located by the sea and able to receive large quantities of imported coal.
To date, 1.5 Mt/year of all-raw coke is produced from around 2.1 Mt of moist coal, producing 600 to 750 Mm

Statistical and economic data
After remaining more or less stable at around 350 Mt per year until 2000, annual world coke production has been growing significantly since the beginning of the 21st century. It was around 455 in 2005, 595 in 2010 and 685 Mt in 2013.
This growth can be attributed entirely to China, whose coke production rose from 120 in 2000 to 243 in 2005, 390 in 2010 and 476 Mt in 2013. China's...
